Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a parent-child guard system used for a security alarm device or the like that monitors illegal intrusion and issues an alarm.
[0002]
[Prior art]
Conventionally, when guarding an office and a plurality of areas adjacent to the office (there may be a plurality of warehouses), the following two configuration methods have been taken.
[0003]
In the first method (hereinafter referred to as the first conventional technology), the office and the warehouse are set as separate security areas, and the security state is switched and the security is switched. An operating device is installed. When switching to the security state of the office and the warehouse at night and in the morning, the security state is switched by operating the operating devices of the office and the warehouse, respectively. When there is a carry-in to the warehouse during the night security state, the operation unit installed in the warehouse is operated to bring only the warehouse into a security-released state and carry in.
[0004]
In the second method (hereinafter referred to as “second prior art”), the office and the warehouse are guarded as the same security area, and the guard state switching operation device is installed in the office and the warehouse. Even if is operated, the security status of both security areas is switched. When switching between the security state of the office and the warehouse at night and in the morning, the security state can be switched by operating one of the operating devices of the office or the warehouse. If there is a carry-in to the warehouse during the nighttime security state, operating the operating device installed in the warehouse to release the security state of the warehouse will simultaneously release the security state of the office.
[0005]
Japanese Laid-Open Patent Publication No. 61-272898 discloses a plurality of slave units respectively arranged at a plurality of monitor locations, and a master for identifying a monitor location and detecting the presence or absence of an intrusion according to a signal from each slave unit. An intrusion monitoring device composed of a machine has been proposed. Hereinafter, this known technique is referred to as a third conventional technique.
[0006]
The intrusion monitoring device can divide the monitoring location into multiple zones and perform intrusion monitoring by zone, and the master unit is provided with a monitoring ON / OFF switch that individually turns ON / OFF the monitoring function for multiple zones, The slave unit is provided with a zone selection switch for selecting a desired zone from a plurality of zones and a partial release switch for temporarily stopping transmission of the monitoring signal.
[0007]
The slave unit is provided by selecting an arbitrary zone with the zone selection switch for each slave unit installed at the monitoring location and turning on / off the monitoring function of the corresponding zone with the monitor ON / OFF switch of the master unit. Intrusion monitoring at different monitoring locations is performed by zone. If it is desired to partially cancel monitoring at an arbitrary monitoring location during monitoring, it can be performed by turning on the partial release switch of the slave unit installed at the monitoring location where monitoring is to be canceled.
[0008]
[Problems to be solved by the invention]
In the first prior art described above, since the security state is switched separately between the office and the warehouse, if there is a carry-in to the warehouse during the night-time guard state, only the warehouse is brought into the security-released state and carried in. Although it is possible to prevent outsiders from entering the office, it is necessary to switch between a plurality of security states when switching the security state between the office and the warehouse at night and in the morning. In this case, a key is often used for the switching operation device, which causes problems in storage and carrying.
[0009]
In the second prior art described above, when switching to the security state of the office and warehouse at night and in the morning, it can be switched by operating either the office or warehouse controller. When the warehouse is loaded into the warehouse, if the warehouse is operated by operating the controller and the security of the warehouse is released, the office is also in a security-released state, and there is a problem that the confidentiality of the office cannot be maintained.
[0010]
In the third prior art described above, the intrusion monitoring apparatus divides the monitoring location into a plurality of zones, and performs security by switching ON / OFF of monitoring for each zone. For example, when guarding an office and a warehouse adjacent to the office (there may be a plurality of warehouses), when the office and the warehouse are guarded at night, a plurality of security state switching operations are required. Also, when releasing the security of the warehouse for loading during nighttime security, the security state is canceled with the partial release switch of the slave unit, and the carry-in is carried out, but after returning, return without returning the partial release switch If this happens, there is a problem that only the monitoring location is not monitored even during night security until you realize that you forgot to switch the switch.
[0011]
[Means for Solving the Problems]
According to the present invention, at least one parent security area as a main security area and at least one child security area as another security area, a group of sensors for detecting abnormalities such as fire and intrusion, Installed in the parent guard area and the child guard area, between the start / release of guard, the sensor group status display, the voice output function, between the parent guard area side operator and the child guard area side operator In a parent-child guard system configured to be provided with a guard terminal device provided with a control unit and an interface unit and connected to a general subscriber telephone line or a dedicated line, any of the parent guard area side operation devices is operated. If there is a child security area that is released when the parent security area is set to the security state, the child security area in the released state is switched to the security state, and the child security area is Rear guard state switching device the parent guard area is controlled by the control unit to allow only when in security,
When there is a child area that is in a guarded security state when operating any of the parent equipment area side controllers to bring the parent area into a security unlocked state, the child security area in the guarded state is switched to a released state. A parent-child security system is obtained.
[0012]
Further, according to the present invention, when the guard state of the parent guard area is the guard release, when the guard state of the child guard area is switched from the guard release to the guard when the guard is released, it is operated as a guard switching abnormality. A parent-child guard system is obtained in which an abnormality warning is notified to a child guard area-side controller connected to the child guard area.
[0013]
Further, according to the present invention, when the guard state of the parent guard area is switched to guarding with the parent guard area side controller, the control unit starts monitoring the parent guard area side sensor group, and the parent guard When the guard state of the parent guard area and the child guard area is different due to the switching of the guard state of the area side controller, the control unit makes the guard state of the child guard area the same as the guard state of the parent guard area. If there is a response to the sensor group during the guard state of the parent guard area and the child guard area, the control unit determines that the guard is abnormal and alerts the monitoring center via the interface unit. A parent-child guard system characterized by sending out is obtained.
[0014]
Furthermore, according to the present invention, when the guard state of the parent guard area and the child guard area is guarding, when the guard state of the child guard area is canceled by the child guard area side controller, When the control unit stops monitoring by the child security area side sensor group and enters a security release state, and then again sets the security state of the child security area with the child security area side controller, the control unit A parent-child guard system characterized by resuming monitoring by the child guard area side sensor group is obtained.
[0015]
Furthermore, according to the present invention, when the guard state of the parent guard area and the child guard area is guarding, when the guard state of the child guard area is canceled by the child guard area side controller, When the control unit stops monitoring by the child security area side sensor group and enters a security release state, and then again sets the security state of the child security area with the child security area side controller, the control unit A parent-child guard system characterized by resuming monitoring by the child guard area side sensor group is obtained.
[0016]
[Action]
When guarding multiple security areas with a machine security terminal device, configure the main security area as a parent security area and the other security areas as child security areas, and switch the security status of the parent security area to guard the child security area. The status is also switched to the same security status as the parent security area, and the security status switching of the child security area can be performed only when the parent security area is in the security status, and if it is performed when the security is released, it is efficiently guarded by notifying an abnormal warning The state can be switched. In other words, when switching between the security status of the office and the warehouse at night and in the morning, it is not necessary to switch between multiple security statuses, and the security of the warehouse can be released only when the office is in security, thus maintaining confidentiality of the office. I can keep it.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
The present invention is a system having a machine security terminal device connected to a general subscriber telephone line or a dedicated line, and has a function of automatically reporting a security start / release signal and a security abnormality signal to a security company monitoring center.
[0018]
When the security switching key box connected to the machine security terminal device is operated to the security side, the monitoring center is connected to the line, the security start signal and its own identification signal are transmitted to the monitoring center, and the line is opened when transmission is completed. And wait in a guarded state. In addition, when various detectors (fire, illegal intrusion, etc.) provided for the security target detect an abnormality after the start of security, the monitoring center and the line are connected in the same way as at the time of the security start, and the alarm abnormality signal and its own identification signal Send. When the monitoring center receives this security abnormality signal and identification signal, it displays the name of the security destination and the type of security abnormality on the display device of the monitoring center, and responds by urging the security guard or reporting to the police or the fire department. . Also, in the case of security release, a release signal and an identification signal are transmitted to the monitoring center, as in the case of the start of security.
[0019]
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1 and FIG. 1 and 2, an operation unit 4 having a security start / release, a sensor status display, a voice output function, and a sensor group 6 for detecting abnormalities such as fire and intrusion are installed in an office (parent security area). Similarly, the operation device 5 and the sensor group 7 are installed in a warehouse (child guard area).
[0020]
Next, the operation of the present invention will be described. If the operation unit 4 is operated to the security side when the security state of the parent security area is the security release, the control unit 2 starts monitoring the sensor group 6 and the parent security area is in the security state. Here, when the guard state of the parent guard area and the child guard area are different due to the switching operation of the guard state of the operation device 4, the control unit 2 changes the guard state of the child guard area to the same guard state as the parent guard area. Switch (the security status of the parent security area and the child security area is the same). If there is a reaction in the sensor group 6 and the sensor group 7 while each security area is in a security state, the control unit 2 determines that there is a security abnormality and sends an alarm to the monitoring center via the local line interface unit 3. Further, if the operation device 4 is operated to the security release side when the parent security area is guarded, the same operation as when switching to the guard is performed and the security is released.
[0021]
Only when the guard state of the parent guard area and the child guard area is guarding, when the operation unit 5 is operated to the guard release side, the control unit 2 stops monitoring the sensor group 7 and enters the guard release state. Thereafter, when the operating device 5 is operated to the security side, the control unit 2 starts monitoring the sensor group 7 again, and enters a security state.
[0022]
If the controller 5 is operated to the security release side when the security status of the parent security area is released, the control unit 2 determines that the security switching is abnormal, and an alarm sound is transmitted from the operator 5 to indicate that the security status is not switched. .
[0023]
Therefore, for example, when guarding an office and a warehouse adjacent to the office (there may be a plurality of warehouses), when switching the office and the warehouse to a guarded state at night, the office (parent If you operate with the controller in the security area), both the office and the warehouse will be switched to the security state, and when you want to release the security only for the warehouse for loading during the security state, operate the controller in the warehouse (child guard area) By doing so, only the warehouse can be unlocked, and the security state can be switched efficiently. In addition, even if you return without returning to the security state after the completion of delivery, if you switch to the security state with the operation device of the office (parent security area) at night the next day, all the security areas will be in the security state. Switch.
[0024]
【The invention's effect】
According to the present invention, when switching between the security state of the office and the warehouse at night and in the morning, it is not necessary to switch between a plurality of security states, and the security of the warehouse can be released only when the office is guarded. Can keep confidentiality.
